Description

[0001] This case is a divisional application of the parent case with the patent application number 202210300635.8, application date 2022-03-24, and titled "Automatic milling and drilling and tapping equipment for cutting boards and their processing methods". Technical Field

[0002] The invention relates to the technical field of plate processing, and in particular to a method for automatic edge milling and drilling and tapping of cutting boards. Background Art

[0003] The chopping board is in the shape of a rectangular parallelepiped, and each side of the chopping board needs to be milled during fine processing. Since the chopping board has 12 sides, in order to improve the milling efficiency of a single chopping board, the existing technology usually uses a conveyor belt to continuously transport the chopping board, and uses a trimming milling cutter on the side of the conveyor belt to mill the edge of the chopping board. Compared with the traditional manual milling method, this method improves the milling efficiency, but the above processing method can only mill the four side edges in the width or length direction of the chopping board at a time, and it is difficult to achieve high-precision trimming of the four side edges in the thickness direction of the chopping board on the assembly line. If the above-mentioned conveyor belt is used to continuously transport the chopping board to mill the side edges in the thickness direction of the chopping board, the chopping board needs to be transported upright on the conveyor belt. This method is difficult to limit, is prone to material jamming, and is difficult to ensure processing accuracy and consistency, and has a high defective rate. Therefore, the above method is not applicable.

[0004] Moreover, during the processing of the chopping board, it is generally necessary to connect a metal hanger for hanging on one side of the chopping board, that is, it is necessary to drill and tap on one side of the chopping board so that the metal hanger can be fixed to the screw hole with screws. However, this step cannot be completed at the same time as the milling of the chopping board. Additional mechanical equipment is required to complete it, and a complicated unloading and loading process is required in the middle, resulting in low work efficiency and high processing costs.

[0005] Therefore, how to complete the milling of the 12 edges of the cutting board and the drilling and tapping of one side of the cutting board in one process using a single device has become a technical problem that needs to be solved urgently. Summary of the Invention
